Leners Poem No. 92,932, dated .my '27, Iseo.

The Schedule referredto in these Letters Patent and-making part of the same.

- had vto the Vannexed drawings, making a partofA this specification, in which- Figure No. 1 is a longitudinal View.

Figures 2, 3, Il, 5, 6, transverse and detached sections ofthe same.

First, the kettles or, as here shown, are placed on a brick foundation, in a graduated scale and form, as shown by Fig. No. 1, so that so soon as it is desirable that the evaporated cane-juice or other product he transferred to the next in order, (they being numbered 1, 2, 3,- 4,) by pressing down the lever b the sluice-gate c is opened, allowing the juice lto ow freely from one to another, avoiding thus the method, now generally in use, of dippingA with buckets.

Second, the two kettles on a level plane next to the smoke-stack, and named" as shown, (Grrand,)v are the ones to receive the raw juice as it flows from the mill. They must be emptied alternately, and for that pur- 1poseA a copper pipe of sufiicient dimensions, as shown, passing 'completely through the second kettle, and opened by similar process of sluice-gatel lever, 8vo., letters b C.

Third, as' it is absolutely necessary, in the manufacture of sugar, to cleanse the juice, a skimming-gutter is provided to each kettle, letter E, in which skimmings are conveyed from the kettles, and from thence through the pipe f into the -main skimmingfguttervg, conveying the. same to. any kind of recipient fitted to the purpose. I

Fourth, the kettles being full of juice, tire is started in the furnace h. .The heatis conveyed under each kettle through the gradually-expanding ue passing under each of them, and being larger at the further extremity', (letter K; its course is also marked by ilying arrows thus, by the repeated elbows, checking its too rapidv draught, and securing the greatest amount of heat to a given sulface. 4

Fifth, in order to enable the sugar-boiler or. of other product to better govern his furnace, a damper, l, is adjusted at the termination of the fine, before reaching the smoke-stack, this damper working on a pir t completely outof reach of the re, and soconstruct as to open or shut the flue gradually on both sides equally, by turning the handle m, (see Figs. N cs. l, 2, 3,) thc damper'being lsoconstruotcd as to resist the heat to which it may be subjected. y

Sixth, in the setting of kettles, two dil'erent-plans are here submitted, igs. 5 and' 6. Fig. 5 admits. by

vits construction exposing a much larger heatng-sur l face, of a much more rapid evaporation of the juice,

but in some cases, where the cane or' other mills have but little power, iig. 6 may be betteradapted. Fig. 5 is built with sloping sides, so as to obtain a side flue, letter n, whereas iig. 6 is so built as only to allow the bottom surface exposed to the heat.

Seventh, the kettles are so constructed that the method now in use, of lining the'same'with bricks, is here avoided. The kettles here shown,` letter o, arel made of same material, the whole forming a'complete kettle, thus avoiding all brick'liuing, as now generally in use, iig. 4.

Claims.

What we claim as our invention or improvement, and desire to secure byLetters Patent, is-

1. The setting of square kettlesiu a graduated scale and position, as shown, with the expanding flue corresponding, for the purpose '0f' evaporatng can@ juice or other product substantiall the same; also the two methods of setting the same..

2. Also, the pivot-damper, as here constructed and applied, in sugar or other evaporating-apparatus, the whole operating and being substantially the same.
